radiation protection monitor Articles

Introduction The energy level of some types of radiation is high enough so that when they interact with matter they cause the formation of electrically charged particles or ion-pairs and break molecular bonds. These so-called ionising radiations are by their nature potentially harmful to life; at high doses they can be lethal and at lower doses can cause genetic damage. Ionising radiation occurs ...

This article presents a short history of research in nuclear physics as well as of 50 years of nuclear power and radiation protection in Switzerland. After the International Conference 'Atoms for Peace' held in 1955 in Geneva the first research reactor was installed in Switzerland. A national environmental radioactivity monitoring programme was started in 1956. Today some 40% of the electricity ...

Pressures on the environment may occur through chemical, physical and biological agents. The subject of this study is physical agents, where physical fields are examined. Physical fields are part of the natural environment. Depending upon their properties and the surrounding conditions, physical fields are transmitted through the spaces in which we live, potentially affecting human health and ...

Japan's disaster has raised many questions regarding safety of the public. It has served as a wakeup call to the agencies tasked with protecting the public. Not least of these questions, but certainly the most far-reaching is the question of the safety of nuclear power and radiation contamination of air and water. Way back when nuclear power was first established, in the 1960s public opinion was ...

This paper describes changes in Bulgarian legislation concerning the health monitoring of occupationally exposed individuals to ensure the radiation safety and protection of radiation workers. The expert view on the implementation of health monitoring programmes to different occupational groups and assessment of health risk, including molecular-epidemiological analyses, is given. Special ...

Safe drinking water is essential to life on earth. Unfortunately, this vast infrastructure suffers from critical vulnerability. Keeping America safe with continuous real time water monitoring is a vital goal and is currently being addressed for biological and chemical risks. For monitoring of radionuclides in drinking water as recommended in the Safe Drinking Water Act 8, the Clean Water Act 9, ...

Dose values from natural radiation sources in several sites of Sao Paulo City were assessed from environmental outdoor gamma radiation levels, by using CaSO-4:Dy thermoluminescent dosimeters. Twelve monitoring stations were placed in different regions of the town including both urban and outskirts areas and the measurements were carried out quarterly and ...

Post-Fukushima upgrades at Krško in Slovenia (www.nek.si) are being implemented in accordance with the requirements of the national regulator and the plant owners. The first phase, including a passive containment vent filtering system and hydrogen recombiners, a new emergency diesel generator, and a protected store of mobile emergency equipment, is already completed. The next phase in ...

Fracking demands the use of millions of gallons of water, precious drinking water, and sand infused with up to 1,000 different toxic chemicals to fracture the shale rock and release the trapped gas or oil. The wastewater, brine, and sludge are then returned to the surface and in need of disposal. Unfortunately there is not yet a clear and safe method of disposal or storage. Among these chemicals ...

Intelligent dataTaker System from CAS DataLoggers Water disruptions typically occur after a large amount of water has rapidly collected in a catchment area. As a result this water is subject to continual monitoring and testing for a variety of chemical and biological agents as well as clarity, rate of movement, and water levels for environmental management. Turbidity, conductivity, ...

Abstract In this paper information from Water Authorities in the USA, Europe, Middle East and Australia that have purchased permanent monitoring leak detection equipment is reviewed and the findings are presented in a structured format that covers the following: Justification for permanent monitoring Evaluating the different product offerings Selecting the ...

Environmental radioactivity due to radon and its progenies in the ambient air at the vertical 15 UD Pelletron accelerator facility of the Inter University Accelerator Centre, New Delhi, India was evaluated to calculate the annual effective dose to the workers and users. The radon activity was measured with an active monitor. The activity concentrations of the radon progenies were measured ...

This paper deals with a one-week monitoring of the 50 Hz magnetic field on the ground floor and the first floor of houses under 150, 220 and 380 kV high-voltage overhead three-phase AC transmission lines. The field strength varied with the current intensity, the conductor height, and the storey of the house. Because current intensity varies with time the magnetic field depended on the time of day ...

The increasing use of radiation in the medical field is providing great advances in health improvement. However, these techniques can generate an increase in the number of professionals exposed to radiation. The Brazilian authorities (Brazilian Nuclear Energy Commission ? CNEN) have imposed the monitoring of specific body parts of professionals. One of these obligations is the monitoring of the ...

A key element in radiation protection programs at commercial nuclear power plants, nuclear research facilities, fuel fabrication plants and regulatory agency oversight programs of licensees is management's ability to validate the accuracy of the many air sampling instruments utilized in the facility's radiation protection air monitoring programs. The volume of air sampled in each sample ...

The objective of this paper was to develop and produce holders for thermoluminescent detectors for use in interventionist radiology and nuclear medicine. To obtain the value of Dose Equivalent for Extremities, a dosimetry of extremities was done. The holders must have characteristics which are adequate for their intended use. The detector element used in the holders was the LiF:Mg,Ti (TLD-100) ...

Description of the approaches to a decision support system on Risk Based Land Management (RBLM) and rehabilitation of radioactively contaminated territories on the basis of integrating monitoring data, Geographic Information Systems (GIS), models and decision support tools is presented in this paper. The key blocks of the PRANA DSS, developed for scientific and practical needs for model ...

This paper gives a short overview of the activities of the Belgian Nuclear Research Centre (SCK?CEN) and the role it can play in the cooperative agreement that was established between the China National Nuclear Corporation (CNNC) and SCK?CEN. Indeed, the current established cooperation on nuclear energy research between China and Belgium should make use of the nuclear research experiences and ...

The Office of Meteorology and Hydrology in Mexico equipped a vehicle with measurement technology for verification of their Hydro-Met stations. We are proud that they decided to choose our smart WS501 compact weather station (All-in-one) for measurement of the meteorlogical parameters. With the integration of the smart weather sensor WS501-UMB the calibration vehicle can provide accurate data ...
